STORAGE-BATTERY-CASING HANDLE.

Application filed March 5, 1921.

To all whom it may concern:

Be it known that I, CLARENCE W. HAZE- LETT, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Storage- Battery-Casing Handles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention is directed to improvements in storage battery construction, and is particularly concerned with the provision of a novel non-corrosive handle.

The general object of the invention is to provide a handle, which is acid proof, simple in construction and of suflicient strength to withstand the abuse incident to its use in connection with a storage battery casing. Another feature of the invention comprises means for effectively securing the handle to a battery casing.

The invention is more fully set forth in the following description in connection with the accompanying drawings which illustrate a preferred embodiment of my invention, the novel characteristics being summarized in the claims.

In the drawings Fig. 1 is a perspective view of a storage battery handle; while Fig. 2 is a view of the same when assembled on a storage battery casing; Fig. 3 is a cross sectional elevation through the center of the handle and a section of the battery casing, showing the method I use to secure the handle to the casing; Fig. 4 is a view showing the shape of the insulating material used in forming an acid-proof covering on the handle; Figs. 5, 6 and 7, illustrate appropriate apparatus which may be used in forming the handle which will be hereinafter described.

Referring to the various parts by numerals, in Fig. 1, I have shown a battery handle 8 comprised substantially of a duotile steel core member 9, covered by a noncorrosive metallic shield 10. The core may have distorted ends or anchors of any appropriate shape, however, the manufacturing process may be greatly simplified by having serrated ends 11 formed on the core, which are adapted to fit cylindrical openings in the end members 12 of the casing 13. These cavities in the end members are adapted to be filled with molten pitch or a similar Serial No. 449,721.

acid proof cement in which these serrated ends may be pressed, provision being made about the perimeter of the cavities for permitting the surplus cementing material to flow out of the openings and coagulate about the exterior port-ions of the casing and handle, as shown at 14, Fig. 3. These openings may have an enlarged portion 15 into which the ends 16 of the non-corrosive covering may extend, thereby preventing any acid from reaching the corrosive core 9.

A convenient method of forming this handle is as follows A metallic bar 17 of suitable length is placed with the end portion between the serrating rolls 18, two of which may be rigidly secured to the frame 19, while pressure may be brought upon the periphery of the rod by a third serrating roll 20, rotatably mounted on the lever member 21, which is pivotally secured at 22 to the frame 19. The bar may be rotated by any suitable 'means, such as a power driven means, during which period pressure is exerted on the rod by the roll 20, thereby causing the metal to flow and conform to the shape of the rolls thus forming the serrations 23, the outside diameters of which are slightly larger than the normal diameter of the rod. Upon completion of one end of the rod, the other end may be inserted in the apparatus and the performance repeated. The serrated member 17 may then be inserted in the hollow metallic insulating member 24, shown in Fig. 4, which is of sufficient length to cover the unserrated portion of the member 17.

The covered member may now be placed in the bending vice 25, as shown in Fig. 7, and the end members 26 may be bent downwardly to form the covered bar into a U shape as shown in Fig. 1, and Fig. 7, by rotating the levers 27 in a downward direction thus causing the forming rolls 28 to act upon the insulating cover and bend the end portions 26 of the bar and covering about the rolls 29, which are pivotally mounted coaxially with the center of rotation of the bending levers 27. The finished product may then be lifted in a vertical direction from between the forming rolls of the bending device, while the levers are positioned horizontally.

By thus forming a handle having a ductile metallic core with a non-corrosive jacket mounted thereover, I obtain a product which is simple in construction yet of a very serviceable form having considerable durability, which will also be impervious to any acid fumes arising from battery jars. Further more, by having the serrated ends 23 embedded in the walls of the casing by means of pitch or other acid-proof cement, the serrated ends act as an anchoring means to rigidly secure the handle to the casing. Likewise, by having the ends of the noncorrosive jacket extending into the casing walls a slight distance, I eliminate all possibility of spilled acid reaching the corrosive core.

Having thus described my invention, I claim:

1. The combination with a battery casing, of a handle therefor comprising a core with a non-corrosive covering, said core extending beyond the covering, and such extended portion occupying a hole in the wall of the casing, said hole having an enlarged counterbored portion about its entrance, and the covering occupying such counter-bored portion.

2. A battery casing having a downwardly extendingopening in one of its vertical walls leading from the top edge of such wall, and a handle comprising a core and a non-corrosive covering surrounding the core, the core extending beyond the end of the covering, such projecting portion of the core occupying said opening and acid proofing material within the opening.

3. A battery casing having a downwardly extending opening in one of its vertical walls leading from the top edge of such wall, and a handle comprising a metallic core and a non-corrosive metallic tube surrounding the. core, the core extending beyond the end of the tube and being there shouldered, such projecting portion of the core and the immediately adjacent portion of the tube occupying said opening, and acid proofing material surrounding such end portion of the tube.

4:. An article of the class described comprising a box, a U-shaped handle having serrated end portions occupying openings in the wall of the box, said handle comprising a metallic core and a tubular encasement of non-corrosive material, both portions extending into the holes in the box walls.

5. The combination of a battery casing having substantially vertical holes in the end walls thereof filled with an acid proofing material, and a handle therefor comprising a metallic rod having distorted end portions adapted to be embedded in said acid proofing material, said handle having a noncorrosive jacket terminating in the upper portions of said holes.

6. The combination with a battery casing, of a handle therefor, comprising a rod surrounded by an intermediately located noncorrosive tube, the projecting ends of the rod being provided with shoulders and the two ends of the rod and the adjacent end portions of the tube occupying holes in one of the walls of the casing.

7. In a battery casing of the character de scribed, the combination of end walls having counter-bored holes formed therein, a U- shaped handle comprising an inner member having end portions adapted to be forced into the smaller portions of the holes and a jacket surrounding said inner member and extending into said counter-bored portions of the holes.

8. In a battery casing of the character described, the combination of end walls having counter-bored holes formed therein, a U- shaped handle comprising an inner metallic member having end portions adapted to be forced into the smaller portions of the holes and a tubular jacket surrounding said inner member and extending into said counterbored portions of the holes, and acid proof-- ing material in the holes surrounding the ends of the jacket and sealing the holes.

9. In a battery casing of the character described, the combination of a substantially U-shaped handle comprising a metallic core and a non-corrosive covering surrounding the core including a portion of the legs, and a casing wall having holes formed therein adaptable for the reception of the uncovered portions of the core legs and the end portions of said non-corrosive covering, whereby the holes may be sealed with acid proofing material prior to the insertion of the handle legs therein and subsequently form a seal between the walls of the holes and the ends of the non-corrosive covering surrounding the core.

10. In a battery casing of the character described, the combination of a casing wall having holes formed therein, said holes being enlarged at the top, and a handle com-- prising an inner metallic U-shaped core having the legs thereof distorted to provide engaging edges adapted to grip the Walls of the holes, and a tubular covering surrounding said metallic core and having the ends thereof extending a substantial distance into he casing wall, there being sufficient space between the outer surface of the non-corrosive covering and the walls of the enlarged portions of the holes for the reception of acid proofing material, whereby a seal may be formed between the non-corrosive covering and the casing wall.

11. In a battery casing of the character described, the combination of a casing wall provided with parallel holes extending from the upper surface thereof a substantial distance into the wall, said holes being enlarged adjacent the upper surface, a handle comprising a ductile metallic rod having serrated end portions adapted to be forced into the smaller bore of the holes, and a nonwalls of the enlarged portions of the holes, whereby acid may be prevented from flow- 10 ing along the covering and into contact with the metallic core member.

In testimony whereof, I hereunto afiix my signature.
